    As I hear and read it, backup/restore using a SSD is the same as using a normal HDD.
    And here I have a problem understandig how it works.

    Using HDDs, we copy sectors and restore them to the original HDD.
    Does a SSD actually work with sectors?

    Data are stored in flash cells, are they organized like a HD-sector?

    When backing up a SSD to HDD, in what way are the data stored on HDD?
    Restoring them, do the data end up in the same flash cell they were copied from?

    I made backups from SSD, but am somewhat scared to try a restore fearing a big mess :doubt:

    Frank, the internal structure (NAND cells) of the SSD are never seen by the outside world. The SSD maintains its own "allocation" table to translate the OS' block/sector layouts to its own internal organization.

    Restoring should be just fine. The only difference is the partitions in the SSD should be aligned on a 2048 byte boundary, rather than the usual 64-byte boundary used on most HDDs. If the alignment is not right during the restore, it will still work but won't be optimal for the SSD's internal organization.

    Correct alignment is managed automatically by the latest versions of all major imaging and partitioning programs.
